Exciting science and clinical efficacy in this MD Anderson Cancer Center team science study led by Van Morris, MD In Cancer Cell. Triple therapy with IO led to durable responses in BRAF V600E MSS colorectal cancer, showing promise. Randomized study ongoing. #crcsm cell.com/cancer-cell/fu…

Importante la concientizacion sobre cáncer digestivo a edad temprana. Por eso esto se va a discutir en el 1er Congreso en Punta del Este sobre esta problemática en LATAM 10 y 11 sept 2025 instagram.com/reel/DODzpUAiW…

PROMETCO: RW treatment patterns across the mCRC continuum (n=738). Guideline-concordant exposure. Median OS 36.4 mo from dx; 6.6 mo from 3L start. PFS fell 1L→3L, then stable to 6L. Survival aligned with long-term trial data. #mCRC #OncoTwitter #RWE authors.elsevier.com/sd/article/S29…

👏 to MD Anderson Cancer Center -led effort reporting out biomarkers for response to PD1 +/- CTLA4 in MSI-H CRC! Unfortunately not all pts experience benefit, and studies like these directing us on who may vs may not benefit will help identify paths towards future improvements for even
